Question

VFP连续打印问题

A1=VAL(thisform.text4.value)
A2=VAL(thisform.text5.value)
SELE TAOL
SET ORDER TO DHCH
AA_=VAL(单号)

sele * from taol WHERE A1<=AA_ AND AA_<=A2 INTO CURSOR KK1

sele KK1
repo form RPT\taol prev

为什么运行 提示 sele * from taol WHERE A1<=AA_ AND AA_<=A2 INTO CURSOR KK1
这个 数据类型 错误啊`~

单号是 表 TAOL 里面的字段~为字符型的~~

Answer 1

A1=VAL(ALLTRIM(thisform.text4.value))
A2=VAL(ALLTRIM(thisform.text5.value))
SELE TAOL
sele * from taol WHERE VAL(ALLTRIM(单号))>=A1.and.VAL(ALLTRIM(单号))<=A2 order by 单号 into CURSOR KK1
SELECT kk1
REPORT FORM rpt/taol prev
注意：报表数据环境不要添加表
另外报表域控件表达式
如果是单号字段，那么双击它表达式改成单号不要带表名。
